Compilation and monitoring of the on-going research projects on nonexhaust traffic related particle emissions
Questions related to the present document
Q1. Does the table(s) cover the most important aspects regarding on-going projects?
Q2. Is there any additional information that needs to be added?
Please provide comments/suggestion
This document is intended to provide an overview of on-going research projects related to
non-exhaust traffic related emissions. It can serve as a living document for keeping the
group informed about all related activities and will be updated any time new information is
provided. A brief description of these projects is required and shall be given in the Annex.
1. Introduction
GRPE has given the mandate to the PMP informal group to prepare a work programme to
address the issue of traffic related non-exhaust particle emissions.
On the basis of the outcome of a literature survey and of preliminary discussions within the
group, it appeared clear that there are still important knowledge gaps that would require
large projects with a multidisciplinary approach to be filled in.
It also turned out that there are important on-going projects addressing specific issues
related to non-exhaust particle emissions, very often not known outside the involved groups
or organizations.
It is therefore considered essential to collect information on these projects (i.e. objectives,
timing, experimental approach, expected results), and whenever possible to promote an
exchange of information between the PMP group and the main actors of the projects. This
will be mutually beneficial both for the PMP group and the groups involved in the projects in
order to avoid duplication/overlapping of the work. It will also represent an opportunity to
share the knowledge and the experience that has been acquired by the PMP group over
more than 10 years of scientific activity on particle emissions that could be useful to better
focus the activity of the project.
